The necessity of calibration of spatially-spaced frequency standards functioning in the BIS structure was identified and substantiated. On the basis of conducted investigations the authors propose to use developed in the Federal State Unitary Enterprise «SNIIM» tech- nique of calibration standards consisting of frequency BIS, based on the frequency offset estimating algorithm according bezzapros- nyh code and phase trajectory measurements.
